Patented Nov. 21, 1944 UNITED STATES PATENT-OFFICE VEHICLE WHEEL p J Harold Hunt and Harry J. Horn, Lansing, Mich., assignors to Motor Wheel Corporation,

Lansing, Micln, a corporation of Michigan Application r p n s, 1942; Serial nmesmsos This invention relates tovehicle wheels and more particularly to wheels including rims of the type employing removabletire retaining side flanges.

The principal object of this invention is to provide a novel and inexpensive construction and arrangement of the parts of such a wheel. More specifically, the objects include: the provision of raised tire bead seats attheopposite sides of the rim, one of which is removable; the provision of a removable tire retaining sideflange which is integral with a load carrying disk; and the-provision of a novel arrangement of parts whereby the rim, the disk and the removable tire bead seat are all secured in assembled relationby common.

Other objects and advantages of the invention will appear from an examination of the following specification when read in connection with the:

accompanying drawings, wherein I Figure 1 is a side elevation of the Wheel shown inFigure 2; .7 Figure 2 is a sectional view taken on substantially the line 22 of Figure 1;

Figures 3, 4 and 5 are fragmentary elevational periphery the disk is provided with openings therein whichcooperate with the openings in the rimflange I3 to receive the cap screws I6. The disk is preferably indented axially outwardly around each of the openings through which the cap screws extend so that the disk isflexed slightly in that region when the cap screws are threaded home, to provide a lock washer effect H and. prevent loosening of the cap screws.

Radially inwardly of the openings which receivethe capscrews the disk I5 is provided with circumferentially spaced apart axially inwardly extending projections 20 (see Figure 1).

These projections serve to help center the rim upon the diskwhen assembling the parts. I

From theforegoing description it will be apparent that the capscrews I6 constitute the sole means for securing the rim and disk together and for securing the removable tire bead seat I4 in place upon the. rim.- In order to assemble these parts the rim is preferably placed upon its side, the removable tire bead seat is then installed upon the rim thediskqis then placed on the rim flange I3, and finallythe cap. screws I6 ar inand sectional views of a modified form of wheel;

and I Figures 6 and '7 are fragmentary elevational and sectional views respectively of a further modified form of wheel. I I

The wheel shown in Figures .1 and 2 includes a rim I0 having an integral tire retaining side flange -II at one edge thereof and an'integral tapered or raised tire bead seat I2 adjacent the flange I I. At its opposite edge the rim I0 is provided with an integral inturned flange I3 which is tapp d to receive securing means, as hereinafter described. The rim II) is of progressively decreasing circumference in an axially outward direction adjacent the side thereof Where the flange I3 is located. A separate raised tire bead seat I4 is positioned on the rim in the region of the portion of reduced circumference, the progressive reduction in circumference facilitating the installation and removal of the seat which is in the form of a continuous cylinder.

The rim Ill is mounted upon and supported by a load carrying disk I5 which is secured to the rim by means of cap screws I6. The disk I5 is provided with a conventional hub opening I1 and with openings I8 for the reception of securing means to attach the wheel to a hub.

The disk I5 includes a peripheral portion I9 which is formed to provide a tire retaining side flange similar to the flange II. Inwardly of its 1 in proper position.

Provision is made to prevent blowing 01f of o the disk I5 when removing a tire from the rim as might occur when'thetire is partially or fully This is accomplished by providing safety studs 2| which are permanently secured to the rim flange I 3 and extend through openings 22 of the bayonet slot type in the disk I5.

The bayonet openings 22 constitute a relatively large opening in communication with a relatively small opening. The safety stud 2| includes a large heat at its free extremity which is larger than the smaller portion of opening 22 and smaller than the larger portion of the opening. Thus, when disk I5 is installed, asshown in Figure 1, it is necessary to rotate the disk in a clock-wise direction in order to permit its removal from the rim, That is, after the cap screws havebeen removed, the disk must be rotated as just de radially inwardly extending attaching flange 34 The attaching flange 34 is notched at circumferentially spaced points 35, as best shown in Figures 3 and 5, to receive'integr'al profiections. 36 which are formed in the disk' ifi, The pro-' jections 36 cooperate with the notches 35 to cor rectly locate the rim and disk in-circumfierential relation to each other and to center the one relative to the other so as to properly align the studs I 30- with, openings provided for that purpose in the disk 36."

The wheel of Figures 3, 1 and is assembled and disassembrled in the same manner described in connection with the wheel of Figures '1 and. 2.-

Asia the case of the latter wheel, the studs 30" and nuts 31 constitute the sole meansiior detachably connecting th 25 to thedisk 26 and for removabl-y securingthe raised' tire bead seat 29in placeuponthe rim. q

;The construction shown in Figures 6 and $1 is generaly similar to: that shown in Figures 1 and'2. It includes a; rim 3;! having, an. integral tire retaining side flange 38 and a raised. tapered tire bead seat 39 adjacent "one edge thereof. At

the: other edge the is provided',with inturne-d'flange 40 which is tapped to receive cap screWsJlL.

c, The rim 31 is 'supportedby a. load carrying disk 42 includes a iperipherali portion 43 formed to correspond generally to the tire retain.- ingpflange 3.8. Secured to the peripheral "portion 4'3 iby Welds 4:41 is; a. generally L-shaped annulus 1-5 which includes a cylindrical portion m constituti-nga raise-d tire bead seat; Thus, theload. carry-' 1 x 111g disk andthe tire retaining side'flange for. one

side of the rim and the raised tire bead seat for one side of the rim constitute a single unit and are all secured in position relative to the rim 3! by the common securing means 4| 5 The wheel of Figures 6 and '7 is assembled an disassembled in the same manner as described" in connection with the wheel of Figure 1.

From the foregoing it will be apparent that the present invention provides a very simple and inexpensive construction and arrangement of parts which includes a wheel having a removable tire tacilitate the removal and installation of a tire on the rim and which also includes raised the bead seats atth'e opposite sides of the rim, one of 'wliich is removable;
